4 FAQs about Photovoltaic support purlin material requirements

Why do solar panels need a purlin?

Purlins play a direct role in holding solar panels securely in place. By creating a reliable framework, they prevent bending, sagging, or shifting of panels over time. This ensures that the panels maintain their correct angle and orientation, which is essential for maximum sunlight absorption and energy generation.

Why do solar purlins need galvanized steel?

Since solar structures are exposed to outdoor conditions for decades, purlins must be manufactured from high quality galvanized steel or aluminum. Galvanized coatings provide excellent corrosion resistance, protecting the structure from rust and extending its lifespan.

What are purlins used for?

Traditionally used in roofing and steel construction, purlins are now widely adapted for solar energy applications. They serve as intermediate supports between the main beams and the panels, distributing loads evenly and preventing structural deformation. In solar mounting systems, the most common types are C Purlins and Z Purlins.

What are purlins made of?

These structures are typically made of steel or aluminum and must withstand wind, snow, and other environmental stresses. Among the critical components of these structures are purlins, which play a vital role in ensuring strength and efficiency.
